✒Description
Fingerprint sensor module is used as a way to verify identity. It is widely applied to consumer products such as electronic door locks, access control systems, security safes, etc.
This capacitive fingerprint sensor module can store and identify up to 100 fingerprints. It calculates the induced capacitance when a finger is pressed on the sensor. The built-in 32-bit microcontroller executes signal processing with a unique algorithm to complete high-speed fingerprint sampling, template file establishment, identification and other operations.
This module has a rich command set for operating functions such as to enroll/verify/identify fingerprints and so on. It uses UART interface to communicate with external devices. The external controller can operate this module with communication protocols and instructions.
When a finger touches the metal frame of the fingerprint sensor, the build-in touch IC changes its output signal level. A product can reduce standby power consumption by supplying power to the fingerprint sensor module after detecting the signal level change from the touch IC.
